Wow. I’m officially adding another adjective the to the Liberal stereotype: Unstable.
From Chicago Faucet’s lexicon:
unstable. adj. pointing out the deficiencies in Chicago Faucet’s knowledge, and the inconsistencies in his/her reasoning.
Or maybe “Fuzzy Math” is the sort of math practiced by characters in the “Get Fuzzy” comic strip. 
I’d add a serious comment, except that Elvis and mhendo have already said what needs to be said.
